it seems like Sir Hobble / Squire Fuzzmin's behavior has changed over the years. i have been trying to locate these two guys for a couple of days now to turn in my dragon scales. tried speaking to the barbarian chick and the ogre in the outpost, waited 18min, 30min, an hour, nothing. did this half a dozen times. finally just decided to hang out in the outpost with track up. finally Sir Hobble popped East / NE of the outpost.
I ran out to him and Squire was already walking with him. hailed both, neither would stop. tried root and snare, but got a message that neither spells could be cast on either of them (never saw that before). so i just walked with them as I handed in the scales to Squire and voila, Wurmslayer.
i decided to follow them, they were headed straight west towards DL. as they walked west they pathed through countless drachnids and surprisingly neither Hobble, Fuzz or the spiders seemed to care that the other was there. eventually they made it to the tunnel, walk about halfway in and stopped at +95, +4667, -149
after a short pause, they turned around and went back out the way they came. again, walking through spiders, frogloks and goblins without any issue. eventually they walked far enough east and stopped at -365, -521, +33.56, just south of the drolvarg fort (kind of small to be a fort) - i think this may be where he spawned when i first saw him on track, although by the time i ran out to meet him (from outpost) he had made his way a little more west than that location.
again after a short pause they turned around and headed west to the tunnel, walked in and this time paused a little bit before halfway then turned around and back east they went. at this point i was bored and left. the point of all this is that they did not spawn anywhere near the "brown pit" up north, nor were they near the drolvargs, nor did Hobble start attacking mobs left and right.
